Isn't your definition of malignant narcissism too wide? Having read it, I think that it fits my neighbours, friends, and family to a "t". Everyone seems to be a narcissist to me now!
This is an understandable reaction. All of us have narcissistic TRAITS. Some of us even develop a narcissistic PERSONALITY, or a narcissistic STYLE. Moreover, narcissism is a SPECTRUM of behaviors - from the healthy to the utterly pathological (a condition known as the Narcissistic Personality Disorder, or NPD).
